Description

Holding hearth stream distribution device

Technical field

The present invention relates to a kind of flow distribution device of horizontal casting holding furnace.

Background technology

Late nineteen nineties, constantly perfect along with a large amount of rises of domestic five metals processing enterprise and production technology, many complex structures, the goods that dimensional accuracy is high can be pressed by forge hot and be finished, and the demand of lead and yellow-collation copper rod is heightened.According to this development trend, our company furthers investigate the good hot malleability of brass β phase, takes the lead in developing the horizontal casting rod and substitutes very general at that time hot-rolled rods and extruding rod.Though this new product is an as-cast condition, satisfied the specification requirement that forge hot is pressed fully, receive praises from customers after introducing to the market.But because employing is 300 kilograms of little type of furnaces, one side double fluid traction, and the specification of main goods is greatly restricting production efficiency of products between φ 10～50 and cause the production capacity of separate unit stove lower, bring very big influence for the development of enterprise, so its structure is still waiting further improvement.

Summary of the invention

Technical problem to be solved by this invention is to provide a kind of reasonable in design, easy to operate, scheduling of production flexibility high and can increase substantially the holding hearth stream distribution device of production efficiency at above-mentioned prior art present situation.

The present invention solves the problems of the technologies described above the technical scheme that is adopted: this holding hearth stream distribution device, include body of heater and continuous cast mold, described continuous cast mold is installed on the body of heater, in continuous cast mold, have the continuous casting nib, and this continuous casting nib openably and closably is connected with furnace chamber in the body of heater, it is characterized in that the overall structure that described body of heater is made up of a plurality of boiler faces, and between boiler face and the boiler face angle is arranged, one to two continuous cast mold is installed on each boiler face.

As improvement, described a plurality of boiler faces may be selected to be two, three, four, five, six, seven, eight or more a plurality of boiler face; And on each boiler face, two continuous cast molds that be arranged in parallel can be installed preferably, each continuous cast mold is connected with haulage gear independently, certainly, is installed in the crystallizer on each boiler face, also can one, three or more, specifically can decide as required.

As further improvement, the end that the structure that described continuous casting nib openably and closably is connected with furnace chamber in the body of heater can be preferably the continuous casting nib is connected with the furnace chamber valve, this valve can include valve rod and valve body, described valve body is the bottom that furnace chamber is fixed in accumbency, and have flow pass at valve inner, the outlet of flow pass is connected with continuous casting nib in the continuous cast mold, and the inlet of flow pass is opened in the upper lateral part of valve body inner end, stretch out outside the body of heater on the top of described valve rod, and its lower end can be inserted in the inlet of valve body up or down; Described inlet can be preferably designed to big young taper seat down suitable for reading, and the insert division, lower end of described valve rod is and enter the mouth the little conical cylinder in big bottom, suitable top.

Compared with prior art, the overall structure that the present invention is made up of a plurality of boiler faces because of the body of heater that adopts, hauling machine is staggeredly arranged, each boiler face is equipped with two continuous cast molds, it is second-rate promptly can to distribute on each boiler face, radially distribute, every stream is independently drawn by hauling machine, so do not disturb mutually in the operation, have the advantages that cloth fluxion amount is many, melt temperature even, operation is simple, and dummy ingot speed can be according to the technological requirement regulated at will, thus realized on a holding furnace can the synchronous production plurality of specifications purpose; And the holding furnace boiler face can be selected design according to producing needs, as three six streams, five ten stream, until octahedral 16 streams, also can select 300 kilograms, 750 kilograms, 1500 kilograms, 3000 kilograms and 5000 kilograms with the smelting furnace that holding furnace is supporting, the daily production capacity maximum of separate unit holding furnace can be above 80 tons.So it is comprehensively above-mentioned, holding hearth stream distribution device of the present invention can be according to the needs of output and boiler face reasonable in design, thereby both guaranteed the low-cost production of body of heater, can improve the flexibility of arranging production again, and can enhance productivity significantly, therefore be the very strong intention of a kind of practicality, be worthy of popularization.

The specific embodiment

Embodiment describes in further detail the present invention below in conjunction with accompanying drawing.

As Fig. 1, Fig. 2, Fig. 3, Figure 10 and shown in Figure 11, be the octahedral 16 stream embodiment in the holding hearth stream distribution device of the present invention, include body of heater 2 and continuous cast mold 1, described continuous cast mold 1 is installed on the body of heater 2, in continuous cast mold 1, have continuous casting nib 11, see Figure 10 and shown in Figure 11, and this continuous casting nib 11 is connected with furnace chamber 22 in the body of heater 2 openably and closably.The overall structure that described body of heater 2 is made up of eight boiler faces 21, and between boiler face 21 and the boiler face 21 angle a is arranged, see Fig. 1, Fig. 2 and shown in Figure 3, two continuous cast molds that be arranged in parallel 1 are installed on each boiler face 21, each continuous cast mold 1 is connected with haulage gear independently.Thereby form octahedral 16 flow structures.One end of described continuous casting nib 11 is connected with the valve of furnace chamber 22, this valve includes valve rod 3 and valve body 4, the bottom of furnace chamber 22 is fixed in described valve body 4 accumbency, and have flow pass 41 in valve body 4 inside, the outlet of flow pass 41 is connected with continuous casting nib 11 in the continuous cast mold 1, and the inlet 42 of flow pass 41 is opened in the upper lateral part of valve body 4 inner ends, and stretch out outside the body of heater 2 on the top of described valve rod 3, and its lower end can be inserted in the inlet 42 of valve body 4 up or down.This inlet 42 is big young taper seat 43 down suitable for reading, and the insert division, lower end of described valve rod 3 is and the 42 suitable little conical cylinders in big bottom, top that enter the mouth, and valve mechanism is easy to operate like this, and is high temperature resistant, not fragile, and the life-span is long.
